Glass-blowing machine.



WILLIAM S. TEEPLE, OF WELLSBURG, WEST VIRGINIA.

' GLASS-BLOWING MACHINE.

Specification of Letters Patent.

Patented July 21, 1908.

' Application filed February 28, 1907. Serial No. 359,838.

To all whom it may concern: l

Be it known that I, WILLiAM S. TEnPLE, a citizen of the United Statesof America, residing at VVellsburg, in the county of Brooke and State oi' West Virginia, have invented certain new and useful'Improvements in Gdass-A v Blowing Machines, of which the following is a specification, reference-being had therein' to the accompanying drawing.

This invention relates to glass blowing machines of that type designed for forming glass and blowingthe same -to a desired shape, within a mold. j. Y

Y The present invention is an improvement on av patent granted to myselfand Samuel G. Johnson, for a glass blowing machine, patented April `21st, 1903, No. 726,112, wherein we' disclosed a portable machine comprising a common shaft that can be easily and conveniently operated to lower a mechanism onto a mold, said mechanism comprising a plunger and'blow pi ies, the latter having arrangedftherein ehec valves adapted to be `automatically..opened vwhen .in a lowered position, to subject the contents of the mold to air pressureand form the contents thereof into proper.shape. vIn ythe 4operation of this machine,it was necessary to handle and manuallyl place the molds Abeneath the plunger of the machine.

The present invention aims to provide revolnble disks for supporting a pluralitvof molds, which are successively moved be neathy the plunger of the machine to be opcratediupon thereby. In connection with the revoluble disks, I employ novel :means forrholding` a disk in .a lfixed position and' properly `positioning a vin old beneathA the plunger.

' The detail construction entering into this improvement will be hereinafter more fully described and then specifically pointed out -in `the appended claims. and referring to the drawing formingpart oltliis specification, hkenumerals vof reference ,designate corre-fl spending Y'parts thrmighont the lseveral' views, in whichfzf ff Figure 1 is an elevation partly in section` of a machine constructed in accordance with my invention, Fig. 2 is an enlarged vertical sectional view of the lower end of' one of the blow pipes of the machine, illustrating a check Valve arranged therein, Fig. 3 is an enlarged elevation of an eccentric employed to operate the blow pipe, Fig. 4 is an elevation of an eccentrically inounted "weight for re'- hand operating lever turning a portion of the operating mechanism of the machine to its normal posit-ion after said mechanism has been operated.

In thev accompanying drawings, l designates a trucker-carriage having a table 2, said table at its one end carrying upwardly extending standards 3, upon which is slidably mounted a yoke 4 having trunnon arms 5 connecting with pitman rods 6, one of said rods extending through the table 2 and both of said rods connecting with wrist pins 7 carried by disks 8 mountedupon a shaft 9. The shaft 9 is journaled in hangers 10 carried by the table 2.

A screw 11 passes through the yoke 4 and carries a cross head 12 which is adjustably mounted upon the screw 11v by a jam nut 14. Slidably mounted insaid erosshead are rods 1 5, said rods at their upper ends being provided with Vheads 16 and at their lower ends with a rigid plate 17;- Interposed between the yoke IZend the plate 17 and surrounding the rods 15 are coiled springs 1S.

Mounted uponthe lower end of the screw 11 is a yoke 19 which slides upon the standards 3. The yoke 1QV carries a detachable plunger head `20,-cXtending through the plate 17 and adapted to enter a mold 21.

One end of the shaft 9 is provided with a 22 which is employed for the purpose of operating the mechanism just described. To normally hold the mechanism in the position illustrated in lthe accomj-)anying drawings, lV erccntrically mount upon. the shaft 9,. weights '12%. lho shai't .1

upon its opposite. end is provided-with un eccentric 24 wl ich is connected to a reciprocating rod, said rod extending upwardly through the table 2. The rod '25 extends through an adjustable arni 26 carried by a.

standard 27 of the table 'lho rod 25 carries an adjustable brackohflb having :i ver.

ticallydisposed stand pipe 22), said stand pipe passing tln'ough'the arm 2o :ind being prrwidodwith a conventional form of air Lcoupling 2&0. Upon theldwcr end of the pipe '2h-is .adjusiably mounted a head 31, said headsup-porting a coiled spring 32 which cngagestlu-x bracket 28. v The Yhead 31 is provided with angularly-disposedports 333 communicating with an air chamber 34 forn'icd in said head. Located within said air chamber-and supporting the head is a coiled s ring 35. 'lhe head 31 is ada ped to open a c ieck valve 36 formed inthe lower enlarged end of the pipe 29. I

lOl

lrights extending through one of tric carried by ,the shaft The present' invention resides princi ally in providing the table 2 with t'wo revo uble supporting plates 37, said plates being mounted upon ball bearings 38 surrounding one of the standards 3 and the rod 25.

I lpon said plates are detachably'mounted.

-inoiuoted u on the truck or carriage l. I

have only il ustrated one complete p ate and its moving and stopping devices, but I desire it to be understood that the plates of one in achine will be similarly constiucted.

It is obvious that when the lever 22 is manipulated that the rod 25 and the pluri er 20 wi l be lowered to operate upon the mo ds located beneath the plunger and the head 31.'

After each operation, the plates 37 are revolved to Cplace another mold beneath the head, thus it will be noted that plunger an operating lever, a

y one operation of the vessel can be formewithin a mold while another vessel is being blown.

What I claini and desire to secure by Letters Patent, is

1. A glass-blowing machine comprising a portable table having a plurality of annular bosses, said table further provided with an .annitlar groove surrounding' each .of lthe bosses and 'constituting one-half of a ball race, a shiftable mold-supporting plate sur.- rouiiding each of the bosses and having its lower face formed with an annular groove constituting the other half of -a ball race, bearing balls mounted in said races, a rock shaft supported below the table, a pair of uprights carried by the table, one of said upa reci rocatory plunger head guided bysaid uprig its, a pair ofpitman rods connected with said plunger head, one of said'pitman rods .extending through that bossfthrough which extends an upright, a pair of disks carried by said shaft and connected to the pit man rods, a reciprocatory rod extending through the other of said bosses, an eccensaid last mentioned rods, a blower head carried by said last mentioned. rod, and means extending through the table and engaging a plate for retaining it in shifted position.
